How to define adsorption / desorption on a porous media or any wall surface?

  If you want to define any reaction like adsorption H2O(g) -> H2O(site) or desorption H2O(site) –> H2O(g) then it is to be defined considering the fact that total site density is a conserved number i.e. for each site balance equation site species must be balanced. Thus adsorption or desorption reaction can be modeled in following manner: H2O(g) + O (site) –> H2O (bulk) +O’ (site) (where surface coverage O + surface coverage O’=1) H2O(bulk) + O'(site) –> H2O (g) + O (site) (where surface coverage O + surface coverage O’ =1)
